  • Closeup of terraced moss on a hillside with water dripping from it. Caption: early land plants most likely lived in moist environments.

    The conquest of land by plants and their proliferation is an biologic story. This video highlights the evolution of plants, while also describing the major groupings of modern-day plants. Concepts and terminology include: chloroplasts, photosynthetic pigments, cell wall, green algae, nonvascular plants, vascular plants, gymnosperm, angiosperm, alteration of generations, Bryophyta, Hepaticophyta, Anthocerotophyta, Pteridophyta, Lycophyta, Sphenophyta, Psilotophyta, Coniferophyta, Cycadophyta, Gnetophyta, Ginkgophyta, and Anthophyta.

    3D model of the atom Carbon

    Carbon (from Latin: carbo "coal") is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first (row 2) of six elements in column (group 14), which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent - making four electrons available to form covalent chemical bonds. Three isotopes occur naturally, 12C and 13C being stable while 14C is radioactive, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.

  • A fossil in a rock.`Caption: More than 50 species are brand new to science,

    A research team has found that sweat is better than saliva and tears for noninvasive testing because it provides information much the same as blood. The team has developed Band-Aid-like sensors to collect health information from sweat. Other segments include the evidence that temperature determines sex for some animals, new methods for delaying ice and frost, and a historic discovery of 500 million-year-old fossils. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.

  • Congested city street, hazy with smog. Caption: the emission of carbon dioxide and other greenhouse gases.

    Humanity's appetite for the earth's resources and consumer goods has led to increased levels of carbon dioxide entering the atmosphere, trapping more heat from the sun, and leading to the warming of the atmosphere. Argues that action could and should be taken at both international and political levels. Also addresses the question of what each individual can do to reduce his/her use of nonrenewable energy sources and lower each personal "carbon footprint" on the planet.

  • An industrial plant with multiple smokestacks emitting pollutants. Spanish captions.

    Energy has been essential for the development of human activities from the Industrial Revolution to present day. Over the course of history, human consumption of energy has increased significantly. Currently, society depends largely on nonrenewable energies that come from fossil fuels. However, the increase in greenhouse gas emissions has highlighted the need to change from fossil fuels to renewable energy sources that reduce environmental contamination. Many industries are committing to the development of alternative energy sources that don’t contribute to global warming. Chapter 9 of Air: Climate Change Series.

  • A map titled, Uso de la Tierra. The region depicted is divided into three segments. The larger segment is labeled, Cuenca. The group of smaller regio is labeled, Agricultura. The remaining region in between the first two regions is labeled, Bosque. Spanish Caption: Una oportunidad de crear planes de trabajo a largo plazo.

    This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans. The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.
